Maxim Bublis	30dbcc21a8	Refactor header includes. ... * reduce build time by 25%; * remove circular dependency on `cpp.h` and other headers. * fixes issue with `my_global.h` from mariadbclient which redefines `__attribute__`, that leads to broken STL and GCC intrinsics if `<algorithm>` wasn't included prior including this header; * fixes another issue with redefined `__attribute__` which leads to `_conn_exchange_t` not being aligned to cache line size; * removes `pthread_setstacksize` calls as `my_global.h` redefines `pthread_setstacksize` to be `pthread_dummy(0)` which led to stack size being never adjusted; * add missing include guards to some headers; * remove unused proxysql_hash.h header.	9 years ago
